Description
Technical field
The invention belongs to the protective treatment technical field of concrete material, be specifically related to wear-resisting infiltration stiffening agent of a kind of nano-silicon modified double components and preparation method thereof.
Background technology
Along with the development of economy, technology, concrete has been widely applied to the every field of mankind's activity, becomes the foundation stone of social development.And so, normal concrete, when as terrace and pavement usage, also exists and wears no resistance, has been easy to the problems such as ash, dusting.These problems just feature of concrete itself determine: concrete is from being poured into setting and hardening process, and coarse aggregate sinks, grout floating, causes concrete surface to wear no resistance; Moisture content unnecessary after hydration reaction distributes from inside, causes concrete structure mesoporosity many, and degree of compactness is poor.Extraneous corrosive medium as sour gas etc., easily reacts by hole and concrete, and the structural material of corrosion concrete, or reinforcing bar in corrosion concrete structure, cause that concrete expansion ftractures, and has a strong impact on the security of concrete structure.
At present, the technology that improves concrete abrasion-resistant mainly contains three classes, and the first kind is to lay one deck wearing layer at concrete surface.The high-abrasive materials such as wearing layer can ceramic tile, stone material, but exist, cost is high, construction trouble, floor level changes the problems such as larger, thereby the scope of application is few.Equations of The Second Kind is at coating such as concrete surface epoxy resin coating, carbamide resins.Although have certain wear resistance to improve, coating can not improve concrete intensity, and organic coating film is blocked concrete surface hole completely, cause internal steam freely not discharge, easily cause the film delamination of flaking, in addition, organic coating film is shorter work-ing life, and maintenance cost is high.The 3rd class is to use concrete infiltration stiffening agent.Thereby concrete infiltration stiffening agent is a class can infiltrate concrete pore and react with it and strengthen concrete material.Since there is aqueous silicic acid salt penetration stiffening agent from twentieth century, such technology is developed rapidly.
Aqueous silicic acid salt infiltration stiffening agent comprises aqueous silicic acid sodium, potassium silicate, Magnesium Silicate q-agent, lithium silicate etc., due to preparation and constructional method simple, concrete is had to the effect of good enhancing, Hardening, raising wear resistance, on the terraces such as the large supermarket of the countries such as America and Europe, factory, school, airport, applied decades.But the water-based stiffening agents such as water glass, potassium silicate, Magnesium Silicate q-agent, owing to containing the strong basicity such as sodium, potassium metallic element, pH value, often in 12 left and right, easily forms alkaline matter, salts substances etc. at concrete surface and separates out, and not only affects ground apparent, and cause ground to send out cunning, have a strong impact on use.Although aqueous silicic acid lithium stiffening agent " accumulation of salt in the surface soil " problem is few, but still there is slow (often wanting some months later just to there will be obvious gloss and hardness) of setting rate, and mainly by import, causing price high, product shoddy phenomenon in domestic market is of common occurrence.
Prepare the existing more report of patent of invention of aqueous silicate stiffening agent with aqueous silicate and other function components.CN200910055825.2 discloses taking lithium silicate as major ingredient, and magnesium silicofluoride, silane emulsion, Emulsion acrylic resin, paraffin and water are the stiffening agent preparation method of the second component.Using method is to brush the second component after the first component uses and is dried again.This patented technology is mainly utilized lithium silicate and concrete reaction, plays enhancement.Magnesium silicofluoride, silane emulsion play certain hydrophobic interaction, and Emulsion acrylic resin, paraffin play brightening agent effect.The method exists lithium silicate Hardening speed of response slow, and the brightening agent validity period such as paraffin are shorter, and the miscible effect of various ingredients is bad and occur the problems such as muddy.CN201010543000.8 discloses and has utilized nano silicone colloidal sol to be penetrated in concrete pore, under potassium metaaluminate katalysis, reacts with calcium hydroxide and unhydrated cement, generates the gel of crosslinking structure.The organosilicon that another key ingredient potassium methyl silicate is hydrophobic nature, forms one deck hydrophobic film at concrete surface, reaches dustproof, refuses water effect.The shortcoming existing is mainly that the reaction of silicon sol and calcium hydroxide is slow, and the cross-linking density of the gel of generation is little, and to concrete Hardening DeGrain, wear resisting property does not obviously promote.Thereafter disclosed CN201110354668.2 and CN201110152386.4, crucial composition is all identical with CN201010543000.8 with preparation thinking.The disclosed a kind of concrete curing sealing agent for low-temperature cold store of CN201110405075.4, it prepares thinking is that lithium, titanium, silicon-dioxide and water react under heating condition, generates aqueous lithium based stiffening agent.Except the slower shortcoming of aqueous lithium based stiffening agent and concrete reaction, also there is the problem in the preparation methods such as lithium and water reaction are violent, and security is low.CN201110083155.2 discloses a kind of multifunctional concrete structure durability protective agent and methods for making and using same thereof, and its component is: with/without the compound fluorine siloxane-acrylate copolymer of machine, lithium silicate, water glass, lithium molybdate, sodium tetraborate, sodium sulfate, phenylpropyl alcohol triazole, nano titanium oxide, dehydrated alcohol and water.Concrete and inner reinforcing bar are protected although many-sided, the statement that concrete abrasion-resistant performance does not improve.
Due to organosilicon preferably penetrating quality, good hydrophobic function on concrete, concrete is had to certain provide protection, be the more class Concrete Protective Agent of research in recent years.And simple organosilane or organic silane low polymer, although also can penetrate in concrete, play certain protective effect, but its protective mechanism is mainly to utilize the hydrophobic interaction of silane at concrete surface, and because its polymerization degree is low, often can not form the network-like macromole of crosslinked shape, thereby the filling to concrete pore and enhancement are very weak, more there is no the raising on wear resisting property.Have and as disclosedly in CN200910027824.7 obtain silane low polymer with the alkenyl alkoxy silane polymerization that contains unsaturated double-bond; although good penetrability, water-intake rate are low; weather resistance to concrete structure has provide protection, but does not mention concrete is had to enhancement.Silane prepolymer particularly contains the network-like macromole gel that trifunctional chains or the siloxane prepolymer of four senses link generates after hydrolytic-polymeric reaction, hole in can air free concrete, by the control of monomer structure, proportioning, effect transparent, that hardness is high, glossiness is high, hardness is high that the macromolecular resin of its complete polycondensation can reach, thereby fine is played closed concrete hole, strengthen concrete effect.The disclosed technical scheme of CN200910186739.5 adopts this kind of thinking exactly.The liquid composition of preparation strengthens Hardening successful to concrete surface layer, prevents in addition that dusting from playing the effects such as dirt simultaneously.But, owing to containing hydrochloric acid in the silane prepolymer liquid after the hydrolysis of silane and tetrachloro silicane, cause the poor storage stability of silane pre-polymer, easily further hydrolytic polymerization before use, cause liquid thickening or gel, affected the penetrating quality on concrete or directly can not use.And taking silicone resin as Hardening material, wear resistance does not reach service requirements merely.
